Rocket.Chat

Rocket.Chat is a comprehensive, open source communications platform that combines team chat with voice, video, and collaboration tools. It's designed as a privacy-first alternative to Slack and Discord, letting organizations keep their communications data on their own infrastructure.

Rocket.Chat is a full-featured collaboration suite for organizations: channels, direct messages, team collaboration, and built-in audio/video conferencing — all self-hostable. Discord is primarily a community and gaming chat platform. Rocket.Chat's focus is enterprise security, data ownership, and extensibility rather than consumer community features.

Yes. Rocket.Chat is designed for self-hosting and can be deployed on your own servers using Docker, Kubernetes, or a range of other methods. This keeps all your messages, files, and call data within your own environment — a key reason organizations with strict data protection requirements choose it.

Rocket.Chat includes team messaging, unlimited channels and users, audio and video conferencing, screen sharing, file sharing, guest access, and end-to-end encryption. It also offers thousands of integrations and a large ecosystem of apps and bots.

Rocket.Chat is free and open source (MIT licensed) and can be self-hosted at no cost with unlimited users and channels. Optional paid tiers add advanced features like enterprise support, compliance and governance tools, and premium app integrations.
